Acute Kidney Injury II: Pathophysiology

854
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

243
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury III: Clinical Manifestations

769
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Acute Kidney Injury I: Introduction

519
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute Kidney Injury V: Interprofessional Care

277
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Acute Kidney Injury VI: Nursing Management

362
Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI. During the physical...

Área de la Ciencia:

  • Medicina de Urgencias
  • Nefrología
  • Radiología

Sus antecedentes:

  • La lesión renal atraumática es una condición rara.
  • El dolor en el flanco puede presentarse de forma atípica, imitando problemas musculoesqueléticos.
  • La hemorragia retroperitoneal puede no tener indicadores obvios de trauma externo.

Objetivo del estudio:

  • Destacar un caso raro de lesión renal atraumática.
  • Enfatizar la importancia de considerar la lesión renal en los diferenciales de dolor en el flanco.
  • Discutir los desafíos diagnósticos y el manejo de la hemorragia retroperitoneal.

Principales métodos:

  • Informe de caso de una mujer joven que presenta dolor en el flanco después del ejercicio.
  • Evaluación diagnóstica que incluye ecografía en el punto de atención e imágenes avanzadas.
  • El manejo implicó estabilización hemodinámica y radiología intervencionista.

Principales resultados:

  • Diagnóstico de lesión renal grado V y hemorragia retroperitoneal activa.
  • El paciente se volvió hemodinámicamente inestable, requiriendo protocolo de hemorragia mayor.
  • Embolización exitosa de la arteria renal en un centro terciario.

Conclusiones:

  • Los médicos de urgencias deben considerar la lesión renal en el dolor en el flanco, incluso sin traumatismo.
  • Las modalidades de diagnóstico como la ecografía pueden no ser fiables para el sangrado retroperitoneal.
  • El reconocimiento temprano y el manejo multidisciplinario son clave para lesiones renales raras.
